To all whom, it may concern.-

Be it known that I, WILLIAM N. KIDDER, a citizen of the United States ofAmerica, and a resident of Providence, in the county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Separable Buttons or Studs, of which the following is aspecification.

My invention has relation to improve ments in link or cuff buttons andstuds of the separable typethat is, of a type wherein the buttons orstuds are detachable one from the other.

In the accompanying sheet of drawings, Figure 1 is a side elevation of aseparable button embodying my improvement. Fig. 2 is a partial sideelevation and partial sectional view of a separable button embodying myimprovement, showing the supplemental or auxiliary presser member. Fig.3 is a crosssectional view, enlarged, taken on line a: r of Fig. 1 andFig. 4 is a similar sectional view taken on line 0 0 of Fig. 2. Fig. 5is an enlarged transverse sectional view taken on the line 5 5 of Fig.2.

In my improved separable button or stud A the front head member a has atubular shank a, having an oval or flattened form transversely rigidlysecured to its back. The rear end of said shank or post a, is open tofreely receive the yielding stem 0 about to be described. At or nearsaid open end the shank is cut away transversely on its upper side oredge to form the opening or notch a The rear head member I) of thebutton is detachably secured to the shank of the front a by means of theelongated U-shaped yielding stem 0. The rearend c of the lower arm ofthe stem is soldered or otherwise rigidly secured to the member I), theother or free arm 0 of the stem having a push lug or projection c on itsupper side or edge adapted to automatically spring into said notch a ofthe shank when the parts are in the normal position or relation, asclearly shown in Fig. 2. It will be seen that the stem 0 forms a guideand support for the head I) by bearing snugly against the upper andlower interior surfaces longitudinally of the. shank, therebymaintaining the back head in position and at the same time giving itincreased stability and also preventing it from turning axially. Thetubular shank (1 projects from a boss a on the inner face of thebutton-head a, and the free end of this tubular shank abuts against asmaller boss cr on the inner face of the button-head I), the borethrough the boss a registering with and being substantially of the samesize as the bore in the tubular shank a. The button may be readilyseparated by simply pressing downwardly upon the lug 0 until it is flushwith the adjacent interior surface of the hollow shank, at which instantthe parts are in position to be drawn away from each other in an endwisedirection. V

In some cases it may be desirable to provide the free end a of the stemwith a vertically-bent extension or link a, the upper end of the latterprojecting through a hole formed in the rim of the rear head I), asclearly indicated in Fig. 2. In this case the members a and b may beseparated or unlocked from each other by pressing downwardly upon theexposed end of the said extension n, thereby depressing the said lug 0until it is flush with the shanks interior surface, substantially asbefore stated.

I claim as my invention 1. A separable button comprising twobutton-heads one of which is hollow, and a curved hollow one-piece shankattached to one head and adapted to bear against the other head, saidshank'being formed with a notch near one end, a spring composed of twocurved integral arms, one of said arms being attached to the inner wallof the outer plate of the hollow head, the other of said arms carrying alug adapted to seat in the notch of the shank, said last-named armextending into the hollow head, and a link arranged in the hollow headand engaging said last-named arm and extending through an opening in theperimeter of the hollow head.

2. A separable button comprising two heads, one of which is hollow, anda hollow shank carried by one head and bearing against the other head,said shank being formed with a notch near one end, a spring composed oftwo integral arms, the ends of both said arms being located in saidhollow head and the end of one of said arms being attached Within thehollow head While the other end is free, said free end carrying a lugadapted to seat in the notch in the shank, and

a link arranged in the hollow head, and engaging said free end, andextending through in gpening in the perimeter of the hollow WILLIAM N.KIDDER.
